The dupondius, formerly a two-pound bronze coin, was now orichalcum, valued at half a sestertius and weighing half as much. The half-ounce as, worth half a dupondius, the semis, worth half an as, and the quadrans, worth half a semis, were the first pure copper coins minted in Rome since 84 BC. [3]

However, while the gold and silver issues contained precious metals, the value of a coin could be slightly higher than its precious metal content, so they were not, strictly speaking, equivalent to bullion .

Roman Imperial Coinage, abbreviated RIC, is a British catalogue of Roman Imperial currency, from the time of the Battle of Actium (31 BC) to Late Antiquity in 491 AD. It is the result of many decades of work, from 1923 to 1994, and a successor to the previous 8-volume catalogue compiled by the numismatist Henry Cohen in the 19th century.
Nero as. Following the coinage reform of Augustus in 23 BC, the as was struck in reddish pure copper (instead of bronze), and the sestertius or 'two-and-a-halfer' (originally 2.5 asses, but now four asses) and the dupondius (2 asses) were produced in a golden-colored alloy of bronze known by numismatists as orichalcum.
